My friend recently purchased the Lava O2 smartphone, excited about its features and affordability. However, they quickly became disappointed with its performance. Despite having an octa-core processor and 8 GB of RAM, the device struggled with slow app launches and occasional lag during multitasking. My friend noted that even basic tasks felt sluggish, which was frustrating. They mentioned that while the battery life was decent, the overall experience was marred by the slow performance, especially when compared to other budget smartphones. Ultimately, they felt that the Lava O2 did not live up to their expectations and regretted their purchase.
